Product Description
N42SH Rare Earth Arc Segment Magnet (Inner Diameter South)
This industrial-grade neodymium arc segment is manufactured from high-coercivity NdFeB material optimized for high-temperature operating environments. The N42SH grade provides exceptional thermal stability and high magnetic output, making it a reliable component for precision engineering applications.
Configuration Pairing: This magnet features a specialized South pole orientation on its inner curvature. It is specifically intended to be utilized alongside our primary N42SH Neodymium Arc Magnet ID-North Pole to create the alternating radial fields required for high-performance rotors and magnetic drives.
Technical Specifications & Dimensions:
- Physical Dimensions: 1.5" Outer Diameter (OD) x 1.25" Inner Diameter (ID) x 0.75" Length (L)
- Segment Angle: 45-Degree Arc (Takes 8 segments to complete a full 360° radial ring)
- Magnetic Polarity: Magnetized radially through the thickness with the South Pole on the Inner Diameter (ID-S)
- Surface Finishing: High-grade Ni-Cu-Ni (Nickel-Copper-Nickel) multi-layer plating for superior environmental protection
- Max Operating Temperature: Rated for stable continuous performance up to 150°C (302°F)
Material Properties (NdFeB):
- Br (Max): 12,800 Gauss
- Hci: >= 20 KOe
- Hcb: >=12.4 KOe
- (BH)max: 41-43 MGOe
Common Applications:
Designed primarily for radial magnetic arrays where alternating North and South poles face inward or interact with an internal shaft, including:
- Stator and rotor builds for brushless motors
- Custom magnetic actuators and sensor arrays
- Torque-couplings and fluid pump drives
Safety Note: Neodymium magnets are extremely powerful and brittle. Handle with care to prevent pinching or chipping. Keep away from pacemakers, medical devices, and children.
